3.4.4
Step 3 Low Speed Z-phase Search
The step3 outputs the drive pulse to the home search low speed is configured to the parameter and the
specified direction until the encoder Z-phase signal(nSTOP2) is activated. To execute the low speed search
operation, the home search in low speed is configured as lower value than the start speed.
If the encoder Z-phase signal(nSTOP2) is activated to the constant speed drive, the drive stops immedi-
ately. If the encoder Z-phase signal(nSTOP2) is activated in mode configuration, the deviation counter clear
signal(also, as nOUT0 signal) can come out for a servo motor.
【
Caution
】
①
If the encoder Z-phase signal(nSTOP2) has been already activated before the step3 starts, an error oc
-
curs and the home search ends. Adjust your system to start the step3 only when the encoder Z- phase
signal(nSTOP2) is deactivated.
②
If the limit signal of the detected direction has been already activated before the step3 starts, an error is
occurred and the home search is ended.
③
If the limit signal of the detected direction is activated in use, the detecting operation is stopped and the
home search is ended.
3.4.5
Step 4 High Speed Offset
The step 4 outputs the drive pulses as many as the home search offset to the home search high speed is
configured at the parameter and the specified direction. This is used to move from the mechanical home to
working home. If the step 4 ends, the position counter is reset as zero(or Disable in mode configuration) and
return to home.
3.4.6
Configuration of Home Search Mode
Activate the Mode screen by selecting the Home Search Mode tab. Only X-axis is displayed for PMC-1HS.
3.4.7
Near Home Signal Level(STOP0)
With the step 1, this mode configures the active level of the near home signal(nSTOP0).

Default value
Home Signal Level (nSTOP1)
Low(GEX connection)/High(Open)
Low
Near home signal on each axis is pin #11 of connector CN4 and 5.
For the active level, in case of selecting Low, the detecting operation of the step 1 is started.
If the signal is connected to the GEX, the drive stops evaluating that the signal is active.
In case of High, the drive goes slow and stops evaluating that the opened signal is active.
